Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your
method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the
commented part to a new method, and use the comment as a starting point when coming up with a good name for this
new method.

It seems like $parser->getOption() targeting Redaxscript\Console\Parser::getOption() can also be of type null or string; however, Redaxscript\Console\Command\Backup::_database() does only seem to accept array, maybe add an additional type check?

This check looks at variables that are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.
